HCM Cushion moorland: western facies
Community Description:
Cushion moorland is alpine vegetation in which > 50% of the ground is covered by cushion plants composed of at least one of the five main bolster heath species or the mat-forming sedge genus Oreobolus. The western facies is distinguished by the absence of dominance by Abrotanella forsteroides. The associated vegetation varies, depending on the location and geology of the site. This is one of two benchmarks available to assess the condition of HCM. This is the appropriate benchmark to use in assessing the condition of western facies of the listed Cushion moorland community (Schedule 3A, Nature Conservation Act 2002).

HCM Cushion moorland: Abrotanella forsteroides facies
Community Description:
Cushion moorland is alpine and subalpine vegetation in which > 50% of the ground is covered by cushions plants. The Abrotanella forsteroides facies is distinguished by the dominance of Abrotanella forsteroides and the absence of both Donatia novae-zelandiae and Phyllachne colensoi. Although Dracophyllum minimum may sometimes be important, the Abrotanella facies is distinguished by occurring mainly in a mosaic with highland sedgeland and highland grassy sedgeland species such as Astelia alpina, Baloskion australe, Carpha alpina, Empodisma minus and Poaceae spp. Prostrate and taller shrubs may also be a prominent component of this facies. Although the facies may be found throughout alpine and subalpine areas of Tasmania it most commonly occurs on the Eastern Central Plateau where it often locally dominant in wet areas within broad valley plains, and these patches are often too small to map or may be difficult to distinguish on aerial imagery from adjacent sedgelands, grassy sedgelands and heaths. This is one of two benchmarks available to assess the condition of HCM. It is the appropriate benchmark to use in assessing the condition of Abrotanella forsteroides facies of the listed Cushion moorland community (Schedule 3A, Nature Conservation Act 2002).
